I have had test pipes on my Z. I already know this. There is no clip of the NISMO exhaust with test pipes yet. I have XERD headers right now and there is no resonator and they are long tubes that eliminate the cats. Believe me, I know how they sound with my aftermarket exhaust and with stock and I have heard clips with Stillen, Borla, and others. I want to hear it particularly with the NISMO. Thanks for the help though!

 

my test pipes are not raspy and ricey and i have no resonator...
